Description

Die Erfindung betrifft einen Mitnehmer für Kettenkratzerförderer gemäß den Merkmalen im Oberbegriff von Anspruch 1.The invention relates to a carrier for chain scraper conveyors according to the features in the preamble of claim 1.

Ein Kettenkratzerförderer ist ein Fördermittel, bei dem das Fördergut in einem aus Förderrinnen gebildeten Rinnenstrang durch Mitnehmer eines Kettenbandes bewegt wird. Die Mitnehmer, auch Kratzer genannt, sind an den Fördererketten befestigt. Die Mitnehmer stellen den Eingriff in das Fördergut her und bewegen dieses mit Fördergeschwindigkeiten in Förderrichtung. Nach der Anzahl und Lage der Kettenstränge werden Einkettenförderer, Doppelmittenkettenförderer, Doppelaußenkettenförderer und Dreikettenförderer unterschieden.A scraper chain conveyor is a means of conveyance in which the goods to be conveyed are moved in a channel run made up of conveyor troughs by drivers on a chain belt. The flights, also called scrapers, are attached to the conveyor chains. The carriers engage in the material to be conveyed and move it in the direction of conveyance at conveying speeds. According to the number and position of the chain strands, a distinction is made between single chain conveyors, double center chain conveyors, double outer chain conveyors and triple chain conveyors.

Funktions- und betriebsbedingt unterliegen die Mitnehmer eines Kettenkratzerförderers hohem Verschleiß.Due to their function and operation, the carriers of a scraper chain conveyor are subject to a high level of wear.

Durch die DE 10 2004 038 688 A1 ist ein Mitnehmer nach dem Oberbegriff des Anspruchs 1 bekannt. Insbesondere, ist ein Mitnehmer für Strebförderer bekannt, bei dem die in die Führungen der Förderrinnen bzw. des Rinnenstrangs angreifenden Enden einen Belag aus einem verschleißfesten Material aufweisen. Hierdurch soll der Verschleiß an der Unterseite der Mitnehmerenden verringert werden, wenn der Mitnehmer im unteren Trum bewegt wird und mit seinen Enden auf der seitlichen Führung aufliegt.through the DE 10 2004 038 688 A1 a driver according to the preamble of claim 1 is known. In particular, a driver for face conveyors is known in which the ends engaging in the guides of the conveyor chutes or the chute line have a covering of a wear-resistant material. This is to reduce wear on the underside of the driver ends when the Driver is moved in the lower run and rests with its ends on the lateral guide.

Die DE 33 17 682 A1 offenbart ein Verfahren und eine Vorrichtung zur Teilerneuerung von Mitnehmern in Kettenbändern von Kratzerförderern. Zur Reparatur von verschlissenen Mitnehmern ist vorgesehen, dass an den verschlissenen Enden Material abgetragen wird und dabei eine mit einer Stufe abgesetzte Keilfläche erzeugt wird. Hierauf werden Ersatzstücke aufgeschoben und mit den Mitnehmerenden verschweißt.The DE 33 17 682 A1 discloses a method and a device for partially replacing drivers in chain conveyors of scraper conveyors. In order to repair worn drivers, it is provided that material is removed from the worn ends and a stepped wedge surface is produced in the process. Replacement pieces are pushed onto this and welded to the driver ends.

Zum Stand der Technik zählt ferner durch die CN 205 076 383 U ein Mitnehmer für Kettenkratzerförderer, dessen Kratzerflügel von einem Verschleißschutzkörper umgriffen sind.The state of the art also includes the CN 205 076 383 U a driver for chain scraper conveyors, whose scraper wings are surrounded by a wear protection body.

Der Erfindung liegt, ausgehend vom Stand der Technik, die Aufgabe zugrunde, einen bauteiltechnisch und für den betrieblichen Einsatz, insbesondere hinsichtlich der Verschleißfestigkeit und der Lebensdauer, verbesserten Mitnehmer für Kettenkratzerförderer zu schaffen.Proceeding from the state of the art, the invention is based on the object of creating a driver for chain scraper conveyors that is improved in terms of components and for operational use, in particular with regard to wear resistance and service life.

Die Lösung dieser Aufgabe besteht nach der Erfindung in einem Mitnehmer für Kettenkratzerförderer gemäß den Merkmalen von Anspruch 1.According to the invention, the solution to this problem consists in a carrier for chain scraper conveyors according to the features of claim 1.

Vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Mitnehmers sind Gegenstand der abhängigen Ansprüche 2 bis 11.Advantageous configurations and developments of the driver according to the invention are the subject matter of dependent claims 2 to 11.

Ein Mitnehmer für Kettenkratzerförderer weist einen Mittelabschnitt auf mit einer Kettengliedaufnahme zum Anschließen des Mitnehmers an Kettenglieder einer Fördererkette. Beidseitig an dem Mittelabschnitt des Mitnehmers schließen sich Kratzerflügel an. Jeder Kratzerflügel weist vom Mittelabschnitt ausgehend einen Stegabschnitt und einen gegenüber dem Stegabschnitt verbreiterten Endabschnitt auf.A carrier for chain scraper conveyors has a middle section with a chain link receptacle for connecting the carrier to chain links of a conveyor chain. Scraper blades are attached to both sides of the middle section of the driver. Starting from the middle section, each scraper blade has a web section and an end section which is widened compared to the web section.

An der Unterseite des Stegabschnitts ist ein Verschleißblech vorgesehen, welches ausgehend von einer Stufe an der Unterseite des Mittelabschnitts den Stegabschnitt in Richtung zum Endabschnitt abdeckt.A wear plate is provided on the underside of the web section, which, starting from a step on the underside of the middle section, covers the web section in the direction of the end section.

Diese Maßnahme trägt zu einer erheblichen Steigerung der Lebensdauer eines Mitnehmers bei, und zwar sowohl was die Abriebs- und Verschleißfestigkeit anbelangt als auch das Verhalten beim Gleiten der Mitnehmer in der Förderrinne. Hierdurch ergeben sich auch positive Effekte auf die Fördererleistung.This measure contributes to a considerable increase in the service life of a carrier, both in terms of abrasion and wear resistance and the behavior when the carrier slides in the conveyor chute. This also has positive effects on the conveyor performance.

Eine Ausgestaltung des Verschleißblechs sieht vor, dass dieses einen insbesondere rechteckig konfigurierten Basisabschnitt aufweist mit einem gegen den Basisabschnitt in Richtung zu den Endabschnitten der Kratzerflügel verbreiteten Enden. Hierdurch wird die Unterseite des Mitnehmers an beiden Kratzerflügeln wirksam gegen Verschleiß geschützt und das Gleitverhalten in den Förderrinnen weiter verbessert.One embodiment of the wearing plate provides that it has a base section that is configured in particular as rectangular with an end that is widened towards the base section in the direction of the end sections of the scraper blades. This effectively protects the underside of the driver on both scraper wings against wear and further improves the sliding behavior in the conveyor chutes.

Ein weiterer vorteilhafter Aspekt sieht vor, dass das Verschleißblech sich bis zum Endabschnitt des Kratzerflügels erstreckt und den Endabschnitt zumindest bereichsweise abdeckt. Auch diese Maßnahme erhöht wirksam die Verschleißfestigkeit des Mitnehmers.A further advantageous aspect provides that the wear plate extends to the end section of the scraper blade and at least partially covers the end section. This measure also effectively increases the wear resistance of the driver.

Eine weitere vorteilhafte Ausführungsform eines erfindungsgemäßen Mitnehmers sieht vor, dass jeder Kratzerflügel eine Kratzerspitze aufweist, wobei die Kratzerspitze zumindest bereichsweise vom Verschleißblech abgedeckt ist.A further advantageous embodiment of a driver according to the invention provides that each scraper wing has a scraper tip, the scraper tip being covered at least in regions by the wear plate.

Weiterhin kann an der Oberseite des Endabschnitts eines Kratzerflügels ebenfalls ein Verschleißkörper vorgesehen sein.Furthermore, a wear body can also be provided on the top of the end portion of a scraper blade.

Der Verschleißkörper kann als ein vom Verschleißblech separates Bauteil ausgeführt sein. Hierbei wird der Verschleißkörper auf der Oberseite des Endabschnitts mit diesem stoffschlüssig gefügt.The wear body can be designed as a component separate from the wear plate. In this case, the wearing body is joined to the end section on the upper side in a materially bonded manner.

Möglich ist es weiterhin, dass das Verschleißblech und der Verschleißkörper materialeinheitlich einstückig ausgeführt sind. Der Verschleißkörper ist dann Bestandteil des Verschleißblechs. Dieses deckt die Unterseite des Kratzerflügels ab und erstreckt sich um die Kratzerspitze herum bis auf die Oberseite des Endabschnitts.It is also possible for the wearing plate and the wearing body to be designed in one piece from the same material. The wear body is then part of the wear plate. This covers the underside of the scraper wing and extends around the scraper tip to the top of the tail section.

Die Verschleißkörper an der Oberseite des Endabschnitts schützen den Bereich, der oberseitig mit den Führungen der Förderrinnen in Kontakt gelangt. Zudem liegen die Mitnehmer im Untertrum auf den Verschleißkörpern auf.The wear bodies on the upper side of the end section protect the area that comes into contact with the guides of the conveyor troughs on the upper side. In addition, the carriers in the lower run rest on the wearing parts.

Die Mitnehmer bzw. die Grundkörper der Mitnehmer bestehen aus Kettenstahl oder aus einem Vergütungsstahl, z. B. 42CrMo4.The carrier or the base body of the driver consist of chain steel or a heat-treated steel, e.g. B. 42CrMo4.

Im Rahmen der Erfindung werden Verschleißbleche ebenso wie Verschleißkörper als besonders vorteilhaft und tauglich angesehen, welche aus einem verschleiß- und abriebfesten Stahl bestehen mit einer Brinellhärte von größer oder gleich (≥) 400 HB, insbesondere liegt die Brinellhärte in einem Bereich zwischen 400 HB bis 600 HB.In the context of the invention, wear plates as well as wear bodies are considered to be particularly advantageous and suitable, which consist of a wear-resistant and abrasion-resistant steel with a Brinell hardness of greater than or equal to (≥) 400 HB, in particular the Brinell hardness is in a range between 400 HB and 600 hb

Erfindungsgemäß ist vorgesehen, dass in jedem Kratzerflügel ein sich in dessen Längsrichtung erstreckender Hohlraum vorgesehen ist. Der Hohlraum ist unterseitig vom Verschleißblech abgedeckt.According to the invention it is provided that a cavity extending in the longitudinal direction of each scraper blade is provided. The cavity is covered on the underside by the wear plate.

Diese Ausgestaltung führt zu einer Gewichtsreduzierung der Mitnehmer und damit der gesamten Förderereinrichtung. Bei der großen Anzahl der Mitnehmer ist eine spürbare Gewichtsreduzierung möglich, so dass ggfs. auch die installierte Antriebsleistung gesenkt werden kann.This configuration leads to a reduction in the weight of the drivers and thus of the entire conveyor device. With the large number of carriers, a noticeable weight reduction is possible, so that the installed drive power can also be reduced if necessary.

Möglich ist, dass der Hohlraum mit einem Füllmaterial gefüllt ist, welches leichter als der Werkstoff des Mitnehmers ist, beispielsweise einem porösen oder geschäumten Werkstoff ebenso wie einem Faserwerkstoff.It is possible that the cavity is filled with a filling material that is lighter than the material of the driver, for example a porous or foamed material as well as a fiber material.

Die Verschleißbleche sind vorzugsweise mit den Mitnehmern stoffschlüssig gefügt, insbesondere verschweißt. Hierbei kann ein Verschleißblech umlaufend oder auch nur bereichsweise an der Unterseite eines Mitnehmers gefügt sein.The wear plates are preferably bonded to the drivers, in particular welded. In this case, a wear plate can be joined circumferentially or only in certain areas on the underside of a driver.

Eine vorteilhafte Ausgestaltung sieht vor, dass das Verschleißblech am mittelabschnittsseitigen Ende und/oder an der endabschnittigen Seite vorstehende Vorsprünge aufweist. Die Vorsprünge fungieren als Formschlusselemente und tragen zusätzlich zur stabilen Befestigung des Verschleißblechs an der Unterseite der Kratzerflügel bei. Auch hierdurch wird die Leistungsfähigkeit der Mitnehmer gesteigert.An advantageous embodiment provides that the wear plate has protruding projections on the end on the central section side and/or on the end section side. The projections act as form-fitting elements and also contribute to the stable attachment of the wear plate to the underside of the scraper blades. This also increases the performance of the drivers.
